Claims

[Scope of utility model registration request]

an ejector that sucks air inside the pressure reduction chamber using a flow of compressed air to create a negative pressure inside the pressure reduction chamber; and a check valve that allows air outside the pressure reduction chamber to flow only into the pressure reduction chamber based on the pressure difference between the outside and outside of the pressure reduction chamber. and a vacuum tank that communicates with the pressure reduction chamber via the check valve.
